This invention relates to a cigar-wrapping device and more particularly to the kind of cigar- Wrapping devices comprising a bunch rolling mechanism and a cutter for nicking the end portion of the wrapper.

The end portion of the Wrapper has a shape which is accommodated to that of the cigar tip end. In order to obtain a smooth and correct tip end, the wrapper end portion is provided with an incision. In hitherto used wrapping devices such incisions are executed by a cutter (flicking device or the like) which cuts the wrapper end during the rotary movement of the rolling mechanism. However, when the wrapper is wound about the bunch, its end portion performs not only a movement towards said bunch but also a lateral movement along it. Therefore, on cutting the wrapper end portion whilst applying the wrapper, the knife tends to prevent the wrapper end portion from performing said lateral movement and thus the incision is split and a smooth cigar tip end cannot be obtained.

According to this invention a device is provided by means of which the drawback above mentioned is fully removed and which renders it possible to wind the wrapper about the bunch particularly rapidly, thus obtaining an increased output of finished product.

One object of my invention is to provide automatic means for arresting at a predetermined moment the rotary movement of a bunch rolling mechanism, causing a cutter to nick the wrapper end portion and thereupon starting the rolling mechanism again for completing the wrapping operation.

A further object of my invention is to provide means for imparting to the bunch rolling mec. anism after the nicking operation a velocity higher than previous to said operation.

With these and other minor objects, not specifically mentioned, in View, my invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawing, which forms a part of'this specification, Fig. 1 is a side elevation of the wrapping device embodying the invention. Fig. 2 is an end view, Fig. 3 is a perspective view showing the making-device, and Fig. 4 is an end View of a modification of the wrapping device.

In an embodiment of my invention the bunch rolling mechanism comprises a cluster having rolls 3, to which is imparted rotary movement from a main driving shaft 9 journalled in the 3, Serial No. 664,814, and April 25, 1932 frame 8 and driven in any well known manner.- A cam wheel 10 having two curvatures 42 and 44 respectively is keyed to said shaft as well as a pinionil, which meshes with another pinion 13, rotatably journalled on a rotatable shaft 12. All 6 pinions are shown diagrammatically in Figs. 2 and 4 by means of dash and dotted lines in order to make the drawing clear. The pinion 13 is secured to another pinion 14. An arm 15 is secured to the shaft 12, and its free end carries a roll 17 on a pin 16. One end of a tension spring is connected to the pin 16, its other end being connected to a disc 19 which is rotatably journalled on shaft 9. Said spring forces the roll 17 against the periphery of the cam wheel 10.

Still another arm 20 is keyed to the shaft 12 and its free end carries a coupling member consisting of a pinion 21 permanently meshing with the pinion 14. Thus the arms 15 and 20 form a lever, and pinion 21 meshes indirectly with pinion 11 by the pinions 13 and 14. The four cluster rolls 3 are each carried by a spindle 22 rotatably journalled in pairs of plates 28 each pivoted on a shaft 2'7 keyed to the frame 8. One end of each spindle of the two upper cluster rolls 3 is provided with a pinion 23 and corresponding ends of the spindles of the two lower cluster rolls are also each provided with a pinion 24. Each pair of an upper pinion 23 and a lower one 24 respectively mesh permanently by an intermediate gear 25, so that the pinions 23 and 24 and the gear 25 all intermesh when the cluster is opened for supplying a bunch to it as well as when it is closed. The two pinions 24 mesh each with another pinion 26 rotatably J'ournalled on the shafts 27 and meshing with a joint pinion 29. The pinion 29 is secured to another pinion 30 rotatably journalled on a shaft 31. The pinion 30 meshes with a pinion 32, which meshes with another pinion 33 secured to a pinion 34. Three pinions 35, 36 and 3'? intermesh and pinion 35 meshes with pinion 34. Preferably the pinions 33 and Ski-37 are of the same diameter. A disc 38 is keyed to the shaft 9 and provided with a curved groove 39 having a projecting portion 43. A lever is secured to a shaft '7, journalled in the frame 8, and one of its arms 6 is provided with a cutter or knife 5, which may be fixed to said arm or rotatably journalled on a pin 45 and driven in any convenient manner. The end of the other arm 40 of the lever has a pin 41, which runs in the groove 39 on turning the disc 38.

In the modified embodiment of my invention shown in Fig. 4 the pinions 33-37 are omitted as well as the curvature 44 of the cam wheel 10.

In the operation of the embodiment of my device shown in Figs. 1-3 the main driving shaft 9 runs continuously in the direction of the arrow (Fig. 2). After having received a bunch I the cluster is closed in a well known manner and a wrapper 2 is automatically delivered to the bunch, likewise in a well known manner forming no part of my invention. When part of the wrapper has been wound about the rotating bunch, the lever 15, 20, the cam wheel 10 and the disc 38 occupy the position shown in Fig. 2. The rotary movement of the shaft 9 is transmitted directly from pinion 21 to pinion 32 and further to rolls of the cluster. Having turned so far in the direction of the arrow that the roll 17 under the influence of the spring 18 enters the curvature 42 of the wheel 10, pinion 21 is released from the pinion 32 but preliminarily without engaging any other pinion. Thus the rotary movement of the rolling mechanism stops. Simultaneously the pin 41 is running into projection 43 of the groove 39 so that the lever arm 6 is swung in the direc tion of the arrow (Fig. 3), and knife 5 performs a nicking movement providing the end portion 4 of the wrapper with an incision as shown in Fig. 3.

After the shaft 9 having turned somewhat, the knife 5 is retired as the pin 41 enters again the concentric portion of the groove 39 and the roll 1'7 enters the curvature 44 of the wheel 10 nearer the centre of shaft 9. The arm 20 is thereby swung over to the left so that it engages the pinion 37 for a moment. Thereby the pinion 37 is caused to rotate and rotary movement is transmitted to the cluster in the same direction as before the nicking operation, as is readily shown in Fig. 2. Obviously the velocity of the rotary movement has now been increased as the pinion 34 has a diameter less than that of the pinion 32.

Then the end portion of the wrapper is rapidly and thereby correctly wound about the tip of the bunch.

After having finished the cigar, the shaft 9 has turned still somewhat, and the roll 1'? is now pressed against the concentric part of the wheel 10 and thus forced outwardly so that the arm 20 is swung over somewhat to the right sufficiently to release the pinion 21 from the pinion 3? and engage it with the pinion 32 again, a new bunch is introduced into the cluster and so on.

In the operation of the embodiment of my device shown in Figs. 1 and 4 the roll 1? enters the curvature 42 of the wheel 10 and the nicking operation is performed all in the same manner as previously described. After the nicking operation however the roll 1'7 will ascend again on the concentric part of the wheel 10 and engage pinion 21 with pinion 32, so that the rolling operation is finished at an unvaried velocity.

I do not wish to limit mystelf to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
